b) Mike was asked to prepare an acidic buffer solution. From the raw materials provided, he has performed dilution in order to achieve the desire concentration. Calculate the pH of this buffer when Mike mixed 200 mL of 0.40 M acetic acid (K₁ = 1.80 x 105) with 200 mL of 0.05 M calcium hydroxide solution. Determine the new pH if 15 mL of 0.1 M sodium hydroxide is added to 0.1 L of buffer solution.
